15" PB Display Doesn't Wake Up Sometimes

    Every now and then, when I open the PB lid from being asleep, the computer will wake up, but the display doesn't turn on. I have to close the lid and open it again to get the display to come one.

    When this happens, I have tried turning up the display and pressing the On button, but this does not do anything.

    Anyone have this problem? This is the last Rev. of the Powerbook. Thanks

    Ha, wish I could say that mine would wake simply by closing and opening again. Sometimes i have the same problem, but only solution is to hold down power button for 4 seconds....

    Have you recently installed Tiger? I've noticed this in the last couple of days with my not so late Rev 12" Powerbook.

    Of course, the problem is not reproducible when I venture into my local AppleCentre for help . . .

    THis happened before I had Tiger. I was hoping that it would stop after I put Tiger on, but no...

    are you plugging in or unplugging the power cord while the powerbook is still asleep?

    I get this problem too at times, sometimes a simple close reopen the lid procedure works, other times I have to to a hard reboot.

    When this happens to me (more often than I would like, unfortunately), I have to reboot by pressing the power button for a few seconds.

    I am hoping that someone gives a good solution to it in this thread... ;)

    I think that is the best solution actually.
